Abstract

The ¹³C(α, n) ¹⁶O reaction is believed to be the main neutron source reaction for the s-process in asymptotic giant branch (AGB) stars. The astrophysical S-factors of this reaction have been determined based on an evaluation of the α spectroscopic factor of the 1/2 ⁺ subthreshold state in ¹⁷O (E _x = 6.356 MeV) by using the ¹³C( ¹¹B, ⁷Li) ¹⁷O α transfer reaction. Our result confirms that the 1/2 ⁺ subthreshold resonance is dominant for the ¹³C(α, n) ¹⁶O reaction at low energies of astrophysical interest.
